Last version standalone ConTeXt issue.
by Jaroslav Hajtmar 10 Oct '16

10 Oct '16

Hello ConTeXist. In the latest version ConTeXt it stopped working my macros which contents function he once advised me Taco. It is low level lua code. Can anyone advise me what the problem is, eventually. how to replace Lua code in my function to make it work again? Macros worked at least 6 years and now crashes. Here is my function: function thirddata.handlecsv.texmacroisdefined(macroname) -- check whether macroname macro is defined in ConTeXt -- function is used to test whether the user has defined the macro \macroname. If not, it needs to define any default value if token.csname_name(token.create(macroname)) == macroname then return true else return false end end Is there any alternative (ConTeXt like), which is should be possible use in Lua code? Thanx Jaroslav Hajtmar

For the Mac users: AppleScript to launch ConTeXt in a flexile way
by Thomas Floeren 22 Sep '16

22 Sep '16

Hello, Some months ago I wrote a little AppleScript script with one purpose: It should be a flexible script to launch ConTeXt typesetting, independently of the text editor I’m using and it should be capable to typeset the Product file even if I’m currently editing any component file belonging to that Product file. I used it for some time, I improved it, and I shared it with a collegue who also works with ConText on OSX. We’re still using it, many bugs have been fixed and some features were added. The script proved to be very useful for us and I thought, why not share it with the other Mac-ConTeXt people? So here it is: https://www.wuala.com/tflo/Scripts/Ctx%20Typeset/?key=75QkpizhdpFS As already said, the main purpose of the script is to launch the Ctx typesetting process (short: Ctx) on a file. Regarding the “a file” the script is very configurable and flexible: A) It can launch Ctx on a file currently opened in your text editor. It works with many text editors (BBEdit, MacVim, TextMate, etc.) as long as the editor is the frontmost process. B) It can launch Ctx on the parent Product file of the component file currently being edited. Defining a “Product file” can either be done semi-automatically or by hard-definition with two swappable register slots. C) If no eligible file is opend in an editor it will launch Ctx on the currently selected tex file in the Finder. The options added in the course of time are: A) Usage of a ConTeXt-Beta or a ConTeXt-Current installation, swappable B) Typesetting in the non-interactive shell or in the visible terminal C) Notifications D) Selection of PDF viewer (Skim, Preview, Adobe, …) E) Automatically calling the PDF viewer or not F) Optionally excluding generated PDFs from TM backup G) luatex or luajitex H) Beeps or no beeps, and so on I) Many other things, explained in the Description Also some features (“Tools”) have been added: A) Purging files including generated PDFs B) Info on the used Ctx version C) Updating the Ctx Minimal (Beta or/and Current) and archiving the old one D) Syntax Check E) Make formats, listing fonts, other, … F) Some extras added in the Extras folder (synctex with BBEdit etc.) G) Much more in the Description Some caveats: A) It works only on OS X B) The script is designed to work with 10.9 (Mavericks). It should also work with 10.8 (old notification via 3rdParty is still implemented). C) Out of the box it works only with the so called “ConTeXt Minimal Installation” (aka ConTeXt Standalone). It won’t work with TeXLive installations or any other kind of excessively screwed-up installations. But you can go into the script to make it work with anything. D) In order to get access to any text editor the script makes use of GUI scripting: you have to liberate the rights in the corresponding OS preferences. This may sound risky to you but the code is open so you can assure yourself of what the script does. E) You have to (and you really should!) read the Description that comes with the script. If you are enjoing the script please share it here, if the script is buggy, or doesn’t work for you at all please let me know too, please. Thank you best wishes -- Thomas

TEI to context XML mappings?
by Mica Semrick 14 Aug '16

Reading the docbook thread earlier today reminded me to ask this: Is there any feature or script that anyone can share that will read in an XML document and spit out a blank mapping file? Thanks! -m

SOLVED: too many open files
by Henning Hraban Ramm 19 Jun '16

19 Jun '16

Hi again, in my current songbook project I use t-filter with LilyPond as shown in http://wiki.contextgarden.net/LilyPond with latest beta MkIV on OSX. Every line (system) of notes is included as its own PDF to leave the page breaking to ConTeXt. But since I have some hundred songs with each a few lines, it sums up... I guess ConTeXt keeps every externalfigure open, since I get this error: pages > flushing realpage 70, userpage 70 (c_helpmesee.tex structure > sectioning > TitelKlein @ level 2 : 0.83 -> Help Me See GNU LilyPond 2.16.2 ERROR: In procedure open-file: ERROR: Too many open files: "/Applications/music/LilyPond.app/Contents/Resources/bin/../share/guile/1.8/ice-9/r4rs.scm" LILYPOND > name='lilytemp/prd_alle-temp-lilypond-c_helpmesee.pdf' LILYPOND > including system no.1 LILYPOND > including system no.2 LILYPOND > including system no.3 LILYPOND > including system no.4 LILYPOND > including system no.5 ) (c_hochaufdem.tex </Users/hraban/workspace/liederheft/lilytemp/prd_alle-temp-lilypond-c_helpmesee-1.pdf> </Users/hraban/workspace/liederheft/lilytemp/prd_alle-temp-lilypond-c_helpmesee-2.pdf> </Users/hraban/workspace/liederheft/lilytemp/prd_alle-temp-lilypond-c_helpmesee-3.pdf> </Users/hraban/workspace/liederheft/lilytemp/prd_alle-temp-lilypond-c_helpmesee-4.pdfI/O Error: Couldn't open file '/Users/hraban/workspace/liederheft/lilytemp/prd_alle-temp-lilypond-c_helpmesee-4.pdf': Too many open files. !LuaTeX error: xpdf: reading PDF image failed ==> Fatal error occurred, no output PDF file produced! It works with songbook excerpts (some 30 songs). I don't understand if the error is really from LilyPond or from LuaTeX (I guess the former), and how I would be able to increase the number of possible files (in bash on OSX 10.8.4). So probably it's more a general Unix question than a ConTeXt one, but anyway... ANALYSIS: $ ulimit -n 256 $ sysctl kern.maxfiles kern.maxfiles: 12288 $ sysctl kern.maxfilesperproc kern.maxfilesperproc: 10240 SOLUTION: $ ulimit -S -n 2048 (Properly describing a problem often helps to solve it. I send this for the records, in case someone runs into the same.) Greetlings, Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

LuaTeX finds font, mtxrun --fonts does not list it?
by Sandra Snan 30 May '16

30 May '16

I'm trying to add a ttf font (Futura) so I can use it in ConTeXt. I've ran mtxrun --script fonts --list --all |less looked at a ttf font that was there, copied my Futura ttfs to the same directory it was in, and ran mtxrun --script fonts --reload --force But I still can't find it in mtxrun --script fonts --list --all |less nor can I use it in ConTeXt. (The filenames don't have spaces.) The curious thing is that the luatex cache has it. It's listed in /home/sandra/.texmf-var/luatex-cache/generic/names/luaotfload-names.luc under various names, all starting with "futuralt". Curiously, /home/sandra/.texmf-var/luatex-cache/context/[number]/fonts/otf/futuralt-book.tm[ac] exist. But the only "book-" related name in luaotfload-names.luc is futuraltbook, not futuralt-book. Neither worked in ConTeXt, though. How do I move forward with this, how do I add ttfs so that ConTeXt understand them? Sandra

extended printing options in ConTeXt
by Pablo Rodriguez 29 May '16

29 May '16

Hans, would it be possible to implement two extended printing options defined in the PDF specification? You have kindly implemented duplex printing and page scaling options. At my workplace, we are it on a daily basis for mail merging (I had to make an “extension” to distinguish between duplex printing and page scaling [it isn’t an option for me]). In the present implementation, page, portrait and landscape values sets page scaling to none. In most of the documents we generate, we have to fit page contents to printer margins. It is a must for us, since corporate templates are the way they are (wrong designed). Would it be possible to have the PDF printing options in different keys than the one used for the the viewing options? It would be also extremely useful to be able to specify the number of copies and select page size from PDF document. These are the keys /NumCopies and /PickTrayByPDFSize (described on page 365 from the PDF specification). The keys and their values would be: duplex page portrait landscape (only a duplex key required) fixed (no value is required) copies number pdfsize yes no This way, the user has only to press the OK button in the printing dialog or enter (and forget about selecting which kind of document requires which options). I’m asking this for my own needs (it is essential for us at work, where none knows what ConTeXt might be). But this implementation benefits any ConTeXt user. Many thanks for your help, Pablo -- http://www.ousia.tk

Adjusting Kerning/Spacing between Letter
by Malte Stien 27 May '16

27 May '16

Hi, I am trying to typeset some strings in {\tt ...}, but they turn out to be pretty wide. So, I would like to compress those bits of text a little. Any hints on how I could do that locally, that is without adjusting the entire font. Thank you, Malte.

Support for Optional Content Groups
by Chris Chapman 22 May '16

22 May '16

I am new to ConTeXt (coming from LaTeX), and am really impressed. Great work! I am working on a document that has layers that I want to be screen-only, similar in approach to this: http://tex.stackexchange.com/questions/167846/implementing-full-page-screen… I am assuming that Optional Content Groups would be the best way to do this. How would I set something up like this in ConTeXt/LuaTeX? I know I could make a screen-only version and a print version of the output pdf, but I want to have my cake and eat it too ;) Thanks in advance, Chris Chapman
